Solution for windows platform

1. Uninstall Node
2. Delete folder from programfiles if exist (C:\Program Files\nodejs)
3. Delete npm's data folder: C:\Users{Your uername}\AppData\Roaming\npm

Install node Again(use different installation folder like "C:\Program Files\nodejs-2")

Root cause is node and nvm installed in same installation folder.
